Introduction
SUPIR Upscaler is known for its remarkable ability to enhance realism and fine details, making it the preferred choice for high-resolution image enhancement. In contrast, Ultimate SD Upscale employs advanced algorithms to refine image details and upscale images to higher resolutions, such as 8K, without sacrificing quality or introducing blur. When used together, these tools not only enlarge the image but also significantly improve its overall quality, delivering outstanding clarity and precision to meet the demands of 8K resolution.
SUPIR
The SUPIR_sample node simplifies the sampling process in AI art generation, using the SUPIR model's capabilities to refine latent representations through denoising. It offers customizable settings for sampling steps, noise levels, and conditioning, providing precise control to meet artistic needs. This makes it a versatile tool for creating high-quality, unique visual content.

How to use this workflow?
Step 1: Upload Image
Upload an image to the extension, and WD 1.4 Tagger will process it, generating a list of tags along with their confidence scores.
Step 2: Image Upscaling and Enhancement
The SUPIR Upscaler first enlarges the image to a 2000-pixel resolution, providing a high-quality foundation for further refinement. Next, Ultimate SD Upscale takes advantage of the detailed base image from SUPIR Upscaler, enabling it to upscale the image to 8K resolution with enhanced clarity and precision.
